Tennis takes care of everything. It requires agility and quickness to get to the ball, core strength to get power into your shorts and stamina to last for an entire match. In addition to toning your arms and shoulders, it's a total body workout for your legs and abs, and works your heart and core unlike any other sport.

You're the best in the world, so you deserve those little perks along the way if you can get them.

My workouts include aerobic exercise for a healthy cardiovascular system; strength training to maintain muscle tone and bone density; core strength exercise for a stable mid-section; and stretching to maintain mobility.

When I'm playing my best, like I was at the U.S. Open, I feel on top of the match and able to do exactly what I want. There are other times when you're not in control, but that is tennis and you have momentum changes in every single match.

People think that there is so much money in tennis, but the reality is unless you're ranked in about the top 50 you don't earn much at all. It is hard to support yourself travelling the world, to be away from home most of the year and to pay for a coach to help you become a better player.

Daniel, my big brother, is eight years older. I'm lucky he didn't mind hanging out with his little sister and my younger brother.

I don't really remember the day we lost our home in the floods, but looking back I can understand how devastating it was for my parents. I was only six, so I remember us having to move to Adelaide - but not much of the actual day and night of the flood. We had to start all over again and my parents opened a café.
